Search Beyond Journal Articles
While scholarly journals articles will make up the majority of the sources used in your literature review, there are other sources you may need to include.
This section focuses on some of the most important sources other than journal articles:
- Measurement Instruments
Dissertations contain a wealth of useful information for anyone working on a literature review. The literature review chapter of any dissertation will make an attempt to cover all of the relevant literature on the topic. You can look at that literature review and the dissertation's references to discover sources you may not know about. Seminal literature is often difficult to find, unless you look at dissertations.

Finding a test or measurement instrument can sometimes be difficult and time consuming. The Capella Library has some resources to help you with this search:
- Tests in Print (with MMY)
- Mental Measurements Yearbook
- Health and Psychosocial Instruments
The test and measurement databases listed above have test reviews, which include historical information related to reliability and validity, and contact information for the test's publisher. Not all tests are published, so the contact information may be for the test's creator.
You can also identify tests by looking at articles and dissertations in your field. Many will use an established test, and you may see that some tests are very popular in your field. You can then try to find the actual test.
How do you find a copy of a test or measurement instrument?
- Look in the appendix of a dissertation that uses the instrument. Search the Dissertations & Theses Full Text database to find a dissertation using the instrument.
- Search the web for the test or the test publisher. You may be able to see a preview or sample copy.
Before you use a test or measurement instrument in a research study, make sure you have permission from the publisher or creator. They may require payment for use of the test.
